What the C)HT Label Actually Covers
The acronym C)HT is shared by several unrelated credentials across the industry, so a precise definition matters before you spend a single hour studying. On this site, C)HT refers to the Hardware Technician & Operating Systems Technician credential from Mile2. Mile2's own Terms and Conditions identify C)HT (also written CHT) as Certified Hardware Technician and its companion, C)OST (COST), as Certified Operating Systems Technician. Because the two credentials are taught together and share a single course outline, this site covers both under one roof, which is why you will see the combined title used throughout our materials.
If you have arrived here from a search for the meaning of the abbreviation, our related explainers on what C)HT stands for and the C)HT meaning cover the naming question from other angles. This article focuses on the credential itself: what it tests, how it is delivered, and where it sits in a technician's career.
Who Runs the Credential: Mile2
Mile2 is the governing and administering body. It publishes the course outline, operates the testing platform, sets the renewal rules and issues the credentials. That matters for candidates because every operational question, from identity verification to renewal deadlines, is answered by Mile2 documents rather than by a third-party testing vendor.
Mile2's public catalog also lists the related course pages for the hardware and operating systems courses, and its self-study page describes the offering as two certifications in one course. For a broader orientation to what holding the credential means, see What Is C)HT Certification? and the shorter definition at What Is a C)HT?
Two Credentials, One Combined Course
The combined course outline describes a five-day live class for each credential and 80 CEUs. Those are course measures, not examination time, and it is easy to confuse them. A candidate should read them as the size of the training program, not as a statement about how long the test lasts.
| Credential | Full name | Emphasis |
|---|---|---|
| C)HT | Certified Hardware Technician | Physical components, troubleshooting, peripherals, mobile devices, printers, custom builds, operational procedures |
| C)OST | Certified Operating Systems Technician | Operating systems, Windows management, networking, virtualization and cloud, security, SOHO configuration |
Both halves are published in a single outline, and the topics overlap in places, particularly around networking and protocols. That overlap is deliberate: modern support work rarely stays inside a neat hardware-only or software-only boundary.
The 25 Topic Areas at a Glance
The study map used on this site contains 25 headings. These are the union of Mile2's published, unweighted preparation topics. They are not an official exam-domain count and not an exhaustive exam blueprint, and Mile2's sources publish no percentage weights. Anyone quoting a "domain weight" for this credential is guessing. Our full walkthrough is in the C)HT exam domains guide.
The hardware portion contains the first 14 headings: Troubleshooting; Motherboards and CPUs; Computer Power Supplies; Memory; Computer Expansion; Physical Storage; Input-Output Devices; Display Devices; Network Cables and Connectors; Mobile Devices; Printers and Multifunction Print Devices; Custom Computers; Operational Procedures; and TCP/IP and Transport Protocols. The operating systems portion contains the remaining 11: Operating Systems; Windows Management; Network Basics; Network Protocols; Wireless Networking; Windows Networking; Virtualization and Cloud Computing; Security Principles; Security Technologies; Securing Devices and Data; and SOHO Network Configurations.
The Hardware Half in Detail
The hardware chapters read like the working life of a bench technician, and the ordering is sensible: start with a troubleshooting method, then move component by component through the machine.
Troubleshooting and Operational Procedures
These two headings bracket the hardware material. Troubleshooting is a method; Operational Procedures covers how a technician conducts the work professionally.
- Treat troubleshooting as a repeatable process, not a bag of tricks, since scenario questions reward methodical reasoning.
- Expect to connect procedure to practice: documentation, safe handling and professional conduct belong to the same body of knowledge as the technical topics.
Motherboards, CPUs, Power Supplies and Memory
The core of any desktop or workstation. A candidate should be able to explain how these components depend on one another, not just recognize their names.
- Understand how boards, processors and memory are matched to each other.
- Know what a power supply does for the rest of the system and how power problems show up as symptoms.
Expansion, Storage, Input-Output and Display
These chapters cover what gets added to or attached to a system: cards, drives, peripherals and screens.
- Be fluent in the physical storage technologies the outline covers and the trade-offs between them.
- Connect interfaces and connectors to the devices that use them.
Cables, Mobile Devices, Printers and Custom Computers
The breadth chapters. Network cables and connectors, mobile hardware and printing are everyday support tickets, and the Custom Computers chapter pulls together build decisions.
- The Custom Computers chapter lists Wi-Fi standards and wireless-encryption subsections, so do not skip them as "just a build chapter."
- Printers and multifunction devices are a distinct heading, which signals that print support is treated as a real competency.
For a compact reference once you have worked through the material, the C)HT cheat sheet condenses the must-know facts, and the C)HT study guide lays out a full preparation approach.
The Operating Systems Half in Detail
The C)OST side shifts from boxes and cables to configuration, connectivity and defense. Eleven chapters carry the weight here, and networking and security together account for a large share of the headings.
Operating Systems and Windows Management
The foundation for everything that follows. Candidates should be comfortable with how an operating system is installed, administered and maintained.
- Treat Windows Management as a hands-on topic: tools, settings and administrative tasks you could perform from memory.
Networking: Basics, Protocols, Wireless and Windows Networking
Four headings are devoted to networking, plus TCP/IP and Transport Protocols on the hardware side and SOHO Network Configurations at the end. Networking is the thread that ties both credentials together.
- Build a clear mental model of how protocols layer and interact before memorizing individual details.
- Distinguish wireless networking concepts from the Windows-specific networking chapter.
Virtualization, Cloud and Security
Virtualization and Cloud Computing sits alongside three security headings: Security Principles, Security Technologies, and Securing Devices and Data.
- Learn security as principles first, technologies second, and applied device hardening third, mirroring the outline's own order.
- Expect SOHO Network Configurations to test whether you can apply networking and security knowledge to a small-office scenario.
Exam Format: What the Outline Does and Does Not Say
Here the published material is genuinely ambiguous, and honesty serves you better than a confident-sounding number. The combined outline describes 100 multiple-choice questions, approximately two hours and a 70% minimum grade. However, its exam paragraph is singular, while the credentials are separately named, so it does not unambiguously allocate those figures between the C)HT and C)OST exams. We do not infer an aggregate question count or duration, and neither should you.
The question style is multiple choice, so practice should focus on recognizing the best answer among plausible distractors. For a realistic read on difficulty, see how hard the C)HT exam is, and for what the cut score means, see the C)HT passing score breakdown. We have no verified pass-rate data, so our pass rate article stays qualitative rather than quoting figures.
Registration, Testing and Policy Mechanics
Testing is delivered through Mile2's online Learning Management System, accessed through a Mile2.com account. Mile2's Policies and Procedures document (dated May 26, 2026) identifies the platform as LearnDash and sets out several requirements:
- Identity verification: candidates must verify who they are before testing.
- Policy acceptance: you must accept Mile2's policies as part of the process.
- Training is optional for exam entry: the policy permits certification-exam entry without purchasing Mile2 training.
Key Takeaway
Create your Mile2.com account early and read the Policies and Procedures document before you schedule anything. Identity verification and policy acceptance are gating steps, and discovering them on exam day is avoidable.
One trap deserves a warning. The course-outline page's "Exam Only/Purchase Exam Combo" link leads to an unrelated product, the C)CSA exam combo. That product cannot establish the identity or fee of the C)HT/C)OST exam, so do not use it to price your attempt. We have not found a published C)HT/C)OST exam fee in the sources reviewed, which is why our certification cost article separates confirmed items from unconfirmed ones. Eligibility questions are addressed in C)HT requirements, and scheduling in C)HT exam dates.
Validity and Renewal
Mile2 credentials are valid for three years. Mile2's current Certification Renewal Program and Paths to Renewal pages describe two broad routes:
- The CEU route: a standard cycle of 60 CEUs with documented activities, paid renewal and an ethics attestation.
- The exam route: renewal by passing the latest applicable certification exam.
Mile2's current FAQ lists USD 200 for the U.S. regional CEU renewal path. Eligible candidates in developing regions may qualify for a lower price, and exam-based renewal may cost more.
Who Benefits and Where It Fits
The credential maps to hands-on support roles where one person is expected to handle both the machine and the software on it. Typical beneficiaries include help desk and desktop support staff, field service technicians, IT generalists in small and mid-size organizations, and people at the start of an IT career who want a structured, vendor-published curriculum. The breadth of the 25-topic map is the selling point: it signals competence across hardware, Windows administration, networking fundamentals and basic security rather than deep specialization in one.
We do not publish invented salary figures. If you want to explore role types, see C)HT jobs and the qualitative treatment in the salary guide. For a value judgment on whether the time and money make sense for your situation, read Is the C)HT certification worth it? If you are weighing instructor-led options, C)HT training explains the course side, bearing in mind that exam entry does not require buying Mile2 training.
Sequencing Your Preparation Around the Topic Map
Because Mile2 publishes no domain weights, spread your effort evenly rather than gambling on a "heavy" topic. A sensible order follows dependencies in the material itself:
Hardware foundations
- Troubleshooting method first, since it frames every later topic.
- Motherboards and CPUs, Power Supplies, Memory, Expansion and Physical Storage.
Peripherals, cables and breadth topics
- Input-Output, Display, Network Cables and Connectors, Mobile Devices, Printers.
- Custom Computers, including its Wi-Fi standards and wireless encryption subsections, then Operational Procedures.
Operating systems and networking
- TCP/IP and Transport Protocols, Operating Systems, Windows Management.
- Network Basics, Network Protocols, Wireless Networking, Windows Networking.
Cloud, security and integration
- Virtualization and Cloud Computing, then the three security headings.
- SOHO Network Configurations last, as it pulls networking and security together.
Finish with timed multiple-choice practice. Our practice tests are built for exactly that style of recall, and you can try a free practice test to find the topics that need a second pass. The complete preparation framework is in the C)HT study guide.
